Solitary lung meningioma with synchronous brain nodules: clinical and pathological features

Meningiomas are tumours arising from the meninges that ensheath the central nervous system. They are benign tumours, but can very rarely metastasize. We report a case of pulmonary meningioma diagnosed incidentally with concurrent brain masses in an ex-smoker and discuss the difficulties in surgical decision making in a mass that may have represented lung cancer with brain metastases. We also review the literature reporting pulmonary meningiomas.
